Title

On the Lyapunov spectrum of parabolic maps

Abstract

We investigate the structure of the level sets of Lyapunov exponents by 
means of their Hausdorff dimension. Our analysis covers a class of 
interval maps which includes several non-hyperbolic situations. We also 
study level sets of points with given lower/upper and, in particular, with 
zero lower exponent. This is a joint work with M. Rams, IMPAN
